l is 2 or 1 so it should print something

yet it doesnt print anything

I'm not a complete noob i sort of know what i m doing but now I'm just super mad an astonished liie wtff

This code is undefined behavior

ret[i] doesn't exist.

[wispy bridge]

It seems to work, but you are breaking rules that can result in horrible crashes

Try with a longer string and see for yourself

[serene sleet]

wdym it doesnt exist? do u mean i need to allocate for it? I thought u need not do it with cpp string class

[north turtle]

I mean as long as l is string's length nothing bad should happen right?

Im seminoob

plz explain 😄

[wispy bridge]

@serene sleet You're doing out of bounds access on ret

ret.size() is 0, you aren't allowed to touch any characters at index >= ret.size()

[wheat pond]

You do. What you want is ret.push_back(str[i]);

[wispy bridge]

It just happens to seem to work because of some implementation details for std::string

[north turtle]

Ooooh I see thanku

[wheat pond]

.push_back adds to the end and will allocate as necessary.

[serene sleet]

oh my god yes

cpp is stupid

time to go back to C

SOLVED LOL
